IGNITING DEVICE.

Specification of letters Patent.

Patented Jan. 22, 112th.

Application filed October 17, 1917. Serial No. 197,092.

One of the objects of the invention is to provide an article of manufacture which is simple in construction, durable in use, and which can be manufactured on a commercial scale, or in other words one which is not -so diflicult to produce as to be beyond the reasonable cost of such a contrivance.

- With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement, and construction of parts hereinafter described, pointed out inthe appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which-:-

Figure 1 is a side elevation of an igniter constructed in accordance with this invention; Fig. 2 is a front elevation thereof; and gig. 3 is a section taken on line 3-3 of In the drawings the numeral represents the handle of the device, which, as shown, is preferably made of sheet metal by stamping operations. To the upper end of this ban dle is attached, or there may be made integral with the same, a tube 11, which extends transversel of the said handle and is open at both of its ends. This tube holds the p ophoric material in a manner hereinafter to be described. With the handle are furthermore made inte ral three bearings 12, 13 and 14, which are 1n alinement with each 1 other and serve as journals for a rod 15, ar-

ranged at right angles. to the longitu an.

axis of the tube 11. The portion 16 of the handle, disposed below the bearings men:

tioned, is bent out of the plane of that por tion thereof on which the said bearings are formed. The purpose of this arrangement will appear hereinafter. The rod is pro-. vided below the bearing 14 with a finger piece 17, having a section 18 that is adapted to abut against one of the faces of the handle. A spring 19 is coiled upon the rod between the bearings 13 and 14, one end of said spring, denoted by the numeral 20, hearng against that face of the handle which Is opposite to the one against which the section 18 of the finger piece is adapted to abut; the other end of said spring, denoted by the numeral 21, being attached to the finger piece section 18. That portion of the rod which is disposed above the bearing 12 is quadrangular in cross-section, as clearly shown at 22, and extends through a slumlarly shaped bore 23 in an abradin wheel 24, the peripheral portion of w ich is knurled or roughened. A cotter pin 25 serves to hold the abrading wheel in position upon the rod 15.

The tube 11 receives a short cylinder or pencil 26 of the sparking material, and presents it to the roughened edge of the wheel in position to be acted upon by said roughened abrading surface, the pencil extending radially to the said wheel. The exposed end of the pencil 26' is held in frictional contact with the wheel 24 by the expansive force of a helical spring 27 within the tube. This spring abuts at one end against the said pencil and at the other againsta screw plug 28, the threads of which mesh with interior threads on the said tube. By this plug the tension of the spring may be varied, or increased as the length of the pencil is reduced by abrasion.

The portion 16 of the handle is bent out of the plane of the body portion thereof to permit of a convenient mounting of the rod 15 upon the said handle; that is to say the handle with its bearings may first be finished and the r0d15 inserted after the finishing operations.

In using the implement, the gas is turned on, and the operator holds the upper end of the instrument near the jet of gas. The finger piece 17 is then forced by the fingers of the o erator as far as the handle permits in the dlrection of the arrow shown in Fi 3. This ovement increases e on e return movement, partially rotating the rod and the abrading wheel 24 mounted thereon. In this manner an abrading effect on the pencil is produced, which creates a spark or sparks within the flow of gas, thereby igniting the latter.

What I claim is: 1. A pyrophoric i nitlng device, comprising a handle provi ed with bearings, the

section of said handle located below said bearings being bent out of the plane of the bod portion thereof, a rod rotatably mounte in said bearings, means on said rod for limiting the rotation thereof in both directions and serving also as a finger piece for the manual operation of said rod, an abrading Wheel fixedly attached to said rod, a pencil of spark producing material upon said handle in operative relation to said 'aa aaase Wheel, and a spring opposing the manual rotation of said rod and serving to rotate the same in opposite direction when said finger piece is released.

2. A pyrophorio igniting device, comprising a handle provided With bearings, a rod rotatably mounted in said bearings, means on said rod for limiting the rotation thereof In both directions and serving also as a finger piece for the manual operation of said rod, an abrading wheel fixedly attached to said rod, a pencil of spark producing ma-' terial upon said handle in operative relation to said wheel, and a spring opposing the manual rotation of said rod and serving to rotate the same in opposite direction when said finger piece is released.

Signed at New York, in the county of New York and State of New York, this 13th day of October, A. l). 1917.
